Interesting view. I bought one ( Milwaukee) and I thought it's metal cutting was pretty bad, Sanding, scraping etc., pretty great
I thought so too, so I bought a more expensive cutting blade, so worth the money. You have to go to a real tool shop to get quality, those big box stores just sell the low end stuff at high end prices. That being said, I do and did buy Home Depots Ryobi stuff.
I've had mine for +30 years..... IIRC, I paid about $300 for a kit which included a lot of attachments. If I had to guess it is responsible for the demise of at least 50 fuel tanks over the years! It will cut 1/8" mild steel and 1/4" aluminum like butter. It can plunge cut and has very precise depth control. The small radius blade cuts very close to corners.
